I am currently thinking of buying a Hitachi 42 PD3000. I would like to mount it above my fireplace, but the mantle is higher than average. Could anyone (maybe MAW) as he fits them, give me an idea of the correct mounting height to the bottom of the screen. Also I have quite a small lounge of about 14"x13", is this big enough for a 42" plasma? Many thanks in anticipation.
